Ultrafast Energy Transfer from Photoexcited Tryptophan to the Haem in Cytochrome c

Ultrafast Energy Transfer from Photoexcited Tryptophan to the Haem in Cytochrome c

We report femtosecond Fe K-edge absorption (XAS) and nonresonant X-ray emission (XES) spectra of ferric cytochrome C (Cyt c) upon excitation of the haem (>300 nm) or mixed excitation of the haem and tryptophan (
